Liquid phase sintering is a sintering technique that uses a liquid phase to accelerate the interparticle bonding of the solid phase. In addition to rapid initial particle rearrangement due to capillary forces, mass transport through liquid is generally orders of magnitude faster than through solid, enhancing the diffusional mechanisms that drive densification.

For materials that are difficult to sinter, a process called liquid phase sintering is commonly used. Materials for which liquid phase sintering is common are Si 3 N 4, WC, SiC, and more. Liquid phase sintering is the process of adding an additive to the powder which will melt before the matrix phase.
Molecular crystals, liquid crystals, colloids, micelles, emulsions, phase-separated polymers, thin films and self-assembled monolayers all represent examples of the types of highly ordered structures which are obtained using these techniques. The distinguishing feature of these methods is self-organization in the absence of any external forces.
In this process, the metallic binder improves the toughness of the mould as well as the sintering quality in the liquid phase to fully dense material. [19] Moulds made of hard materials have a typical lifetime of thousands of parts (size dependent) and are cost-effective for volumes of 200-1000+ (depending upon the size of the part).

Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product.

He contributed greatly to methods for processing ceramics, particularly sintering, a method for creating objects out of powders by heating them until they bond. [5] He wrote a series of books on ceramics, culminating in Introduction to Ceramics, a book that became the "founding treatise" for ceramics. [6] Kingery became a full professor in 1962.
